    • A communication processor that is compatible with a plurality of communication protocols while limiting increases in circuit scale is provided. The communication processor includes a computational processing circuit resource having a plurality of programmable function units (FUs). An operation mode determination unit determines an operation mode indicating a communication protocol application state. A permitted processing time determination unit determines a permitted processing time in accordance with the determined operation mode. In accordance with the permitted processing time, a resource allocation unit divides the plurality of FUs and allocates computational resources for each communication protocol indicated by the operation mode. A region controller controls the allocated computation resources. The computational processing circuit resource outputs data from after the computational processing at the timing when the computation processing ends.
    • 提供了在限制电路规模增加的同时与多个通信协议兼容的通信处理器。 通信处理器包括具有多个可编程功能单元(FU)的计算处理电路资源。 操作模式确定单元确定指示通信协议应用状态的操作模式。 允许处理时间确定单元根据确定的操作模式确定允许的处理时间。 根据允许的处理时间,资源分配单元对多个FU进行划分,并为由操作模式指示的每个通信协议分配计算资源。 区域控制器控制分配的计算资源。 计算处理电路资源在计算处理结束的定时从计算处理之后输出数据。

    • In a video signal processing device, an input video signal VO representing a test pattern having two gradations of black and white is converted to 8-bit data by an A/D converter 4 in synchronism with sampling clocks generated in a write-in control circuit 5, and then stored in a memory 6. An MPU 9 reads out picture element data in an effective area of the video signal stored in the memory 6, and calculates the difference AT between the average value of white-level picture element data whose values are larger than a predetermined value and the average value of black-level picture element data whose values are smaller than a predetermined value, and the total variance VT between the variance of the white-level picture element data and the variance of the black-level picture element data. The MPU 9 controls the phase of the sampling clocks generated in the write-in control circuit 5 so that the AT is maximum and the VT is minimum. With this operation, the sampling phase can be automatically adjusted to the optimum value when the video signal is converted to digital data.
    • 在视频信号处理装置中,代表具有黑白两种灰度的测试图形的输入视频信号VO与A / D转换器4同步地与写入控制电路中产生的采样时钟同步地转换为8位数据 5,然后存储在存储器6中。 MPU9读出存储在存储器6中的视频信号的有效区域中的像素数据,并且计算其值大于预定值的白电平图像元数据的平均值与平均值之间的差ΔT 其值小于预定值的黑电平图像元素数据以及白电平图像元素数据的方差与黑电平图像元素数据的方差之间的总方差VT。 MPU9控制在写入控制电路5中产生的采样时钟的相位,使得AT最大,VT最小。 通过此操作,当视频信号转换为数字数据时,采样相位可以自动调整为最佳值。
